Abstract
The utility model relates to an embedded type pin, which comprises a pin body. The pin body is composed of a plastic body embedded section, a transition section and a welding section, wherein the plastic body embedded section is used for fixedly connecting a plastic body and a pin, the transition section is used for electrical connection, and the welding section is used for connecting the pin and a circuit board in tin soldering mode. The biggest cross section area of the top of the embedded section is larger than that of the middle of the embedded section. Due to the fact that the biggest cross section area of the top of the embedded section is larger than that of the middle of the embedded section, the pin is enabled to be welded into a T shape or a 7 shape, contact area and wrapped glue area of the welding section of the pin and the plastic body are increased, a hole expansion condition of the plastic body caused by high temperature influence is avoided, fastness of a device using the pin is improved, and service life of the device using the pin is prolonged.
Description
Technical field
The utility model relates to the electric connection technical field, relates in particular to a kind of flush type PIN pin that is applied to transformer framework.
Background technology
PIN pin as shown in Figure 1; Be vertical cyclindrical shape; Comprise PIN script body; Said body by the changeover portion (2 ') that is used for fixing the plastic cement body buried section (1 ') that connects plastic cement body and PIN pin, is used to electrically connect be used for the welding section (3 ') that the PIN pin is connected with wiring board scolding tin and form plastic cement body buried section (1 '), changeover portion (2 ') and welding section (3 ') integrated molding setting.
In the transformer production process, need with tin on the solder furnace of 390 °-410 ° of PIN pin immersions, because the PIN pin is the C5191 phosphor bronze; Has good thermal conductivity; Be prone to receive heat conduction to give the plastic cement body moment, the plastic cement body back that is heated very easily forms the situation of reaming in plastic cement body and PIN pin junction, cause the plastic cement body buried section (1 ') of PIN pin and being connected of plastic cement body to be become flexible; The PIN pin is dropped, cause transformer fault.
Summary of the invention
The utility model technical problem to be solved is the problems referred to above that exist to existing PIN pin, and a kind of flush type PIN pin is provided.
For addressing the above problem, the technical scheme of the utility model is:
A kind of flush type PIN pin; Comprise PIN script body; Said PIN script body by the changeover portion that is used for fixing the plastic cement body buried section that connects plastic cement body and PIN pin, is used to electrically connect be used for the PIN pin and form with the welding section that wiring board scolding tin is connected, the maximum cross-section area at top, said buried section is greater than the maximum cross-section area in the middle part of the buried section.
Preferably, top, said buried section is the cuboid of laterally placing, and the length of cuboid is greater than the width at middle part, buried section, and said PIN pin integrated molding also is " T " font.
Preferably, said PIN pin is " 7 " font.
Top, the buried section the maximum cross-section area of the utility model flush type PIN pin is greater than the center cross-sectional area; Make the weldering of PIN pin be " T " font or " 7 " font; Increase the contact area of PIN pin welding section and plastic cement body and wrapped up in the glue area; Avoid receiving temperatures involved to make the reaming situation of plastic cement body generation, improved the fastness and the useful life of using this PIN pin device.

Embodiment
Below in conjunction with accompanying drawing and embodiment further explain the utility model, but the protection range of the utility model is not limited to this.
Embodiment 1:
With reference to Fig. 2; The flush type PIN pin of the utility model; Comprise PIN script body; Said PIN script body by the changeover portion 2 that is used for fixing the plastic cement body buried section 1 that connects plastic cement body and PIN pin, is used to electrically connect be used for the welding section 3 that the PIN pin is connected with wiring board scolding tin and form, said buried section 1, changeover portion 2 and welding section 3 integrated moldings.1 top, said buried section is the cuboid of laterally placing; Middle part, buried section, changeover portion 2 and welding section 3 are uniform integral type cylinder; The cross-sectional area of said cuboid is greater than the cross-sectional area of cylinder; The length of cuboid is greater than the length of cylinder, and the maximum cross-section area of cuboid is greater than the maximum cross-section area at 1 middle part, buried section, and said PIN pin integrated molding also is " T " font.
With reference to Fig. 4, be the user mode structural representation of flush type PIN pin at field transformer, PIN pin 5 is fixedly connected with plastic cement body 4 through plastic cement body buried section 1, and changeover portion 2 exposes outside with welding section 3.Buried section 1 is " T " font and has effectively avoided the problem that the PIN pin is loosening and drop.
Embodiment 2:
With reference to Fig. 3; The flush type PIN pin of the utility model; Comprise PIN script body; Said PIN script body by the changeover portion 2 that is used for fixing the plastic cement body buried section 1 that connects plastic cement body and PIN pin, is used to electrically connect be used for the welding section 3 that the PIN pin is connected with wiring board scolding tin and form, said buried section 1, changeover portion 2 and welding section 3 integrated moldings, said PIN pin is " 7 " font.
Claims (3)
1. flush type PIN pin; Comprise PIN script body; Said PIN script body by the changeover portion that is used for fixing the plastic cement body buried section that connects plastic cement body and PIN pin, is used to electrically connect be used for the PIN pin and form with the welding section that wiring board scolding tin is connected; It is characterized in that the maximum cross-section area at top, said buried section is greater than the maximum cross-section area at middle part, buried section.
2. flush type PIN pin according to claim 1 is characterized in that, top, said buried section is the cuboid of laterally placing, and the length of cuboid is greater than the width at middle part, buried section, and said PIN pin integrated molding also is " T " font.
